Solution

1. Preparation

Gather tools and materials.
Disconnect the vehicle battery to ensure safety during repairs.

2. Fuse Inspection

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the power window fuse and inspect it for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Switch Testing

Remove the power window switch panel using a trim removal tool.
Disconnect the switch connector and use a multimeter to test for voltage when the switch is pressed.
If there is no voltage, replace the switch.

4. Motor Testing

Remove the door panel to access the power window motor.
Disconnect the motor wiring harness.
Using jumper wires, connect the motor directly to the battery to check if it operates.
If the motor does not work, replace it.

5. Regulator Inspection

While the door panel is removed, inspect the window regulator for any obstructions, such as debris or broken components.
Manually move the window to see if it is stuck.
If the regulator is faulty, replace it along with the window motor.
